Precatalyzed catalyst compositions, process for preparing epoxy resins, curable compositions, articles resulting from curing the resultant compositions. |
摘要 |
<p>The process of reacting an epoxy resin with a reactive hydrogen-containing compound or a carboxylic acid anhydride in the presence of a phosphonium catalyst is improved by employing a phosphonium compound having an amino substituent on the cation portion of the phosphonium compound as the catalyst. The invention also concerns precatalyzed epoxy resin compositions, curable compositions and cured compositions.</p> |
